Summary:
1. fix possible overflow of the two stats by using uint64_t
2. use a similar source of data to calculate RecordDrop. Previous one is not correct.
Test Plan: See outputs of db_bench settings, and the results look reasonable

Summary:
Now DBTest.DynamicMemtableOptions sets background compaction to be 4, without actually increasing thread pool size (even before the feature of automatic increasing it). To make sure the behavior stays the same after the automatic thread pool increasing, set it back to 1.
Hopefully it can fix the occasional failure of the test.
Test Plan: Run the test

With the patch, thread pool size will be automatically increased if DB's options ask for more parallelism of compactions or flushes.
Too many users have been confused by the API. Change it to make it harder for users to make mistakes

Summary:
This diff is revamping our build tools:
1) Use third-party2 instead of third-party
2) consolidate clang and gcc scripts together, lots of duplication there
3) remove hdfs libs, we never compile rocksdb with them
clang compilation doesn't work yet. It doesn't work in master either. I plan to fix it soon, but I just spent 2 hours trying to make it work and failed. I'll ask experts.
Test Plan: compiles with gcc

Summary:
Long awaited CompactionJob class! Move most compaction-related things from DBImpl to CompactionJob, making CompactionJob easier to test and understand.
Currently this is just replicating exactly the same functionality with as little as change as possible. As future work, we should:
1. Add CompactionJob tests (I think I'll do that tomorrow)
2. Reduce CompactionJob's state that it inherits from DBImpl
3. Figure out how to do yielding to flush better. Currently I implemented a callback as we agreed yesterday, but I don't think it's a good long term solution.
This reduces db_impl.cc from 5000+ LOC to 3400!
Test Plan: make check, will add CompactionJob-specific tests, probably also move some tests from db_test to compaction_job_test

Summary:
TestMemEnv simulates all Env APIs using in-memory data structures.
We can use it to speed up db_test run, which is now reduced ~7mins when it is
enabled.
We can also add features to simulate power/disk failures in the next
step
TestMemEnv is derived from helper/mem_env
mem_env can not be used for rocksdb since some of its APIs do not give
the same results as env_posix. And its file read/write is not thread safe
Test Plan:
make all -j32
